This experiment was investigated from March 20 to September 20, 1960. It was investigated chlorophyll, carotene and ascorbic acid contents of edible plants in Korea, 64 with 132 species belonging to 62 families for the ascorbic acid and 116 species on the 64 families for the chlorophyll and carotene content. Carotene content varies with chlorophyll although the ratio of chlorophyll to carotene was not so high as that obtained by Beak and Redman (1). Where the chlorophyll content is abundant, it appears that the amounts of carotene and ascorbic acid are also plenty.

The present study was performed to investigate antioxidant activities of Korean edible wild extracts. In water and methanol extracts of edible wild plants, total polyphenol content of water and methanol extracts ranged 4.6~183.8 and 8.2~270.1 mg/g, respectively. Radical scavenging activity against DPPH and ABTS radicals was observed to be high in Lysimachia barystachys, Aceriphyllum rossii, Securinega suffruticosa, Sedum kamtschaticum, and Pedicularis resupinata. Pedicularis resupinata, Securinega suffruticosa, Patrinia villosa, and Solidago virga-aurea var. asiatica showed effective SOD-like activity. There was significant correlation between polyphenol content and DPPH and ABTS radical scavenging activities, and SOD-like activity. Plant extracts such as Pedicularis resupinata, Securinega suffruticosa, Rhapontica uniflora, Lysimachia barystachys, and Aceriphyllum rossii had higher polyphenol content, radical scavenging, and SOD-like activity. These results indicate that Korean edible wild plants may be useful as potential antioxidant sources for improving human antioxidant defense system.

Thalictrum rochebrunianum var. grandisepalum (TRG) is a Korean endemic plant, and it is widely used for edible, medicinal, landscape materials. In this study, we examined the protein and mRNA expression levels of MITF, tyrosinase, TRP-1 and TRP-2 by TRG extract (TRGE) in IBMX-treated melanocytes to evaluate the possibility of using TRG as a whitening material. IBMX were reported as melanin synthesis enhancers. It could increase intracellular melanin synthesis by activation of the microphthalmia-associated transcription factor (MITF) signaling pathway. TRGE did not show cytotoxicity at concentrations below $100{\mu}g/ml$ in B16F10 cells. TREG dose-dependently inhibited protein and mRNA levels of MITF, tyrosinase, TRP-1 and TRP-2. Therefore, we suggest that TRGE is an important natural resource for cosmetic raw materials for whitening function.

Five commercially available edible sweeteners are used as diet products because they can replace sucrose. In studies on the effects on animals and the human body, stability has been proven by excreting-oriented studies with characteristics of animal cells, and accumulation in small amounts has been ignored. On the other hand, plants can absorb, degrade, and accumulate foreign substances, so the effect of degradability and accumulation potential can be studied using plants. Metabolic effects in plants of commercially available saccharin and acesulfame potassium (Ace K) were tested using germinated barley and bean sprouts. In germinated barley and bean sprouts, saccharin and ace K showed inhibitory effects on plant growth in all organs from low concentrations in leaves, stems and roots. In addition, it can be observed that the symptoms of death appear clearly over time, so it can be seen that they are accumulated in the body of the plant. As the accumulated amount increases, the toxic effect increases and the plant reaches a state where it is unable to metabolize, turning black from the tip of the leaf and reaching a state of death. In order to remove the accumulated artificial sweetener, recovery was attempted by culturing in distilled water, but it acts as a substance that is not degraded and dies without avoiding toxicity. Saccharin and ace K cannot be excreted from the cell. Its toxic effects are thought to be persistent, inhibiting growth and eventually leading to cell death.

In order to elucidate the antioxidant potential of non-edible parts of oriental melon, antioxidant activities and total phenolic compound contents of six samples including peel, placenta, stem leaf, flesh and seed were determined. Antioxidant activities were evaluated using in vitro DPPH, ABTS, FRAP, and SOD assay. Among non-edible parts of oriental melon, stalk showed the highest antioxidant activity and its antioxidant potential increased significantly in a dose-dependent manner. The contents of total phenolic compound were also higher than other parts. The relationship between antioxidant activities and the contents of total phenolic compound were analyzed and showed higher correlation coefficients between ABTS radical scavenging activity and contents of total phenolic compound. The above results suggest that the stalk of oriental melon may have potential as a good source for functional material.

Five edible mountain vegetables(Saussurea sp. Aster tataricus, A. scaber. Synurus deltoides, Ligularia fischeri) were investigated on the basis of amplified DNA polymorphisms resulted from PCR (polymerase chain reaction) analysis. The sampled plants consisted of 38 individuals in 5 taxa. Only 10 primers out of 62 primers (60 random [10-mer] primers, two 15-mer [M13 core sequence, and (GGAT) sequence]) tested gave rise to polymorphisms in all of the tested plants, producing 176 DAN fragments amplified. Intraspecific polymorphisms found in each taxa showed intraspecies constancy (31.1-61.1%) in the banding patterns of individual plants: Saussurea sp. 31.1%, 15 bands, Aster tataricus, 40.9%, 18 bands, A. scaber. 38.5%, 15 bands. Synurus deltoides, 34.7%, 17 bands, and Ligularia fischeri, 61.1%, 22 brands, respectively. All five species were well classified from each other at the 0.93 level of similarity index value. Intraspecific and interspecific variations were appeared at the levels ranging from 0.62 to 0.99. Based on these results, our PCR analyses support the previous data derived from external morphology of the 5 edible mountain vegetables, but very low levels o intraspecific variations were detected in all of these taxa.

Pleurotus ostreatus, P. eryngii, and Flammulina velutipes are major edible mushrooms that account for over 89% of total mushroom production in Korea. Recently, Agrocybe cylindracea, Hypsizygus marmoreus, and Hericium erinaceu are increasingly being cultivated in mushroom farms. In Korea, the production of edible mushrooms was estimated to be 614,224 ton in 2013. Generally, about 5 kg of mushroom substrate is needed to produce 1 kg of mushroom, and consequently about 25 million tons of spent mushroom substrate (SMS) is produced each year in Korea. Because this massive amount of SMC is unsuitable for reuse in mushroom production, it is either used as garden fertilizer or deposited in landfills, which pollutes the environment. It is reasonably assumed that SMS includes different secondary metabolites and extracellular enzymes produced from mycelia on substrate. Three major groups of enzymes such as cellulases, xylanases, and lignin degrading enzymes are involved in breaking down mushroom substrates. Cellulase and xylanase have been used as the industrial enzymes involving the saccharification of biomass to produce biofuel. In addition, lignin degrading enzymes such as laccases have been used to decolorize the industrial synthetic dyes and remove environmental pollutions such as phenolic compounds. Basidiomycetes produce a large number of biologically active compounds that show antibacterial, antifungal, antiviral, cytotoxic or hallucinogenic activities. However, most previous researches have focused on therapeutics and less on the control of plant diseases. SMS can be considered as an easily available source of active compounds to protect plants from fungal and bacterial infections, helping alleviate the waste disposal problem in the mushroom industry and creating an environmentally friendly method to reduce plant pathogens. We describe extraction of lignocellulytic enzymes and antimicrobial substance from SMSs of different edible mushrooms and their potential applications.

KWON, Oh Yong (Chunju Teacher's Coll.) Partern of the amino acids influedced on nitrogen metabolism of edible bamboo sprouts. Kor. Jour. Bot. VI (4) : 5-10, 1963. It had been scarcely reported by any worker that the essential amino acids to be indispensable in our daily life contained in edible bamboo sprouts and that they had various pattern of free amino acids. For this reason, especially two species of Korean bamboo sprouts collected from the surburb of Chunju, in April, 1963 were used for researching the essential amino acids and free amino acids appeared on paper chromatography. The most suitable part for our edibles was investigated as a part of bio-chemical studies on Korean bamboo sprouts. The free amino acids contained in two species were found as 5-15 kinds and there were a few of difference according to it's growing parts. Many kinds of free amino acids were found in the end parts more than the tip parts and mid parts of bamboo sprouts. Besides, the essential amino acids in each species were found to 3-9 kinds. From the characteristics and the experiments marked above, it was suggested to the author that many kinds of free amino acids in the end part accelerated the formation of nitrogen comounds more than the other parts.
